Problems solved by technology

When afforestation, when digging seedlings from the nursery, it is often easy to dig out the root system because the root system is too long. Sometimes a longer tap root can be dug out, but because there are few root hairs and fine roots, it is difficult to remove it from the soil after afforestation. Under normal circumstances, the survival rate of cork oak seedlings for afforestation is only 30-50%

Embodiment 1

[0074] Embodiment 1: the cultivation of cork oak seedling

[0075] The implementation steps of this embodiment are as follows:

[0076] 1, a kind of cultivation method of cork oak seedling is characterized in that the step of this cultivation method is as follows:

[0077] A. Seed collection and storage

[0078] From September to October of the same year, collect Quercus cork seeds from its excellent stands or excellent trees, and then immediately put them in a ventilated place and spread them out to dry in the shade. Turn them twice a day and dry them until the seed coat turns light yellow, and the water in the seeds disappears to the weight Total 18%.

[0079] B. Seedling selection and seedbed improvement

[0080] Choose the flat river beach in the area below 1500m above sea level in the Bashan Mountains of the Qinling Mountains as the nursery ground; the length of the seedbed is 4m and the width is 1.5m. 25cm and 30cm wide soil corrugated, so that water retention and ma...

Embodiment 2

[0097] Embodiment 2: the cultivation of cork oak seedling

[0098] This embodiment is carried out according to the same mode as embodiment 1, just checks and picks up plump cork oak seeds under the excellent tree, separates 900, changes the different storage methods of cork oak seedling seedlings: (1) dry storage at normal temperature (bag and put in warehouse); (2) low-temperature refrigeration (stored in a refrigerator at -5-1°C); (3) normal temperature sand storage (wet sand); (4) direct sowing in early November. In the spring of the second year (April), check the number of worms and the number of mildew before sowing; then soak the seeds in warm water for 48 hours, sow directly in the nutrient bowl, sow 2 seeds in each nutrient bowl, and check the number of germination in June; then calculate the Insect rate, mildew rate and germination rate.

[0099] The results of its implementation are listed in Table 1.

[0100] Table 1: Effects of different storage methods on the ge...

Embodiment 3

[0103] Embodiment 3: the cultivation of cork oak seedling

[0104] This embodiment is carried out according to the same mode as embodiment 1, just choose full 400 cork oak seeds from the cork oak seeds collected on the excellent tree, be divided into four parts, every part of 100 seeds, adopt 4 kinds of different processes:

[0105] Treatment 1: Sieve the soil of ordinary woodland and put it into a nutrient bowl + soak seeds in warm water;

[0106] Treatment 2: the seedling soil obtained by fully mixing the nutrient soil and the basic soil according to the weight ratio of 2:1;

[0107] Treatment 3: Use treatment 2 soil to sow + 28mg / Kg rooting powder to soak seeds:

[0108] Treatment 4: On the basis of treatment 3, spray rooting powder twice: spray 15 mg / Kg rooting powder when the growth length of the radicle root system of Quercus cork seedlings reaches 1.0 cm and 10 cm, respectively.

[0109] In April, different treatment methods were used to sow in nutrient pots with diff...

Abstract

The invention relates to a method for cultivating cork oak seedlings. The method comprises the steps of collecting and storing seeds, selecting a seedling cultivating field, regulating a seedling bed, preparing seedling cultivating soil, processing the seeds, soaking the seeds in rooting powder, hand sowing in a nutrition pot, spraying rooting powder solution, lifting and transplanting the seedlings and the like. According to the method, through excellent cork oak forest stand or superior tree seed collection, and as the rooting powder is used for soaking the seeds and the prepared soil, and the rooting powder solution is sprayed for two times, the root length of the seedling which is cultivated for 1-2 years is increased by 30%, and the number and length of rootlets are respectively increased by 40%-30%. The seedling cultivating cost is lowered by 30%. The survival rate of cork oak afforestation by seedlings reaches 85%-90%.

Description

【Technical field】 [0001] The invention relates to a tree seedling raising technology. More specifically, the present invention relates to a method for cultivating oak cork seedlings. 【Background technique】 [0002] Cork oak is a precious timber tree species, distributed in 22 provinces and regions in China, of which Qinling and Bashan are the core areas of distribution. The bark of cork oak is the raw material of cork; fruit buds, branches, leaves, and tannin; the large-diameter wood is hard, and it is a precious timber species second only to mahogany. It is very popular in furniture and construction materials, and the small-diameter wood and branches The material is the raw material for the production of high-grade edible fungi. In the income of farmers in the Bashan region of the Qinling Mountains, the income from forest products made of cork oak occupies an important part. The annual output of cork in my country reaches several million tons, of which the main productio...
